"He won't bite anyone like Luis Suarez, but he does have fire," mused Pochettino, who managed Osvaldo at Espanyol. "He has a reputation and he deserves it. He is a player of character who is very emotional.

"But he is growing every day and we are happy with how he is doing, regardless of his behaviour. He is a friendly guy, a good team-mate."

Pochettino added: "It is a good thing for England that he is here, so you can watch him and see how he develops."
